An electroabsorption modulator using a side-entry architecture achieved a contrast ratio exceeding 3 dB over a 3.5 nm range in the C-band, using a voltage swing of 1 V and operating at 1008C. Modulation was due to the quantum-confined Stark effect from ten Ge/SiGe quantum wells epitaxially grown on silicon-on-insulator (SOI) wafers. The device exploits an(More)
Platycryptus undatus (De Geer 1778) (Araneae: Salticidae) stalked and seized insects attracted to porch lamps at night at two sites on Cape Cod, Massachusetts. Ordinarily this spider hunts during the day. Few animals exploit artificial lighting at night for tasks that they ordinarily perform exclusively during the day.
